Quintero, who hasn't seen Grapefruit League action this spring because of his back, said he will get a cortisone shot on Wednesday and return to Houston later that day. If all goes well, Quintero hopes to be back on the practice field Thursday with hopes of playing Friday against the Blue Jays.
"I'm feeling better," Quintero said.
Quintero said trainers told him he could have some inflammation in one of the disks in his back, which could be pinching a nerve and causing discomfort down his right leg.
Meanwhile, third baseman Jimmy Paredes, who has yet to appear in a spring game because of left-wrist inflammation, will face live pitching Tuesday afternoon on one of the Minor League fields. Infielder Angel Sanchez (back), whom manager Brad Mills said isn't as far along in his recovery as Paredes, will take two sets of batting practice with the coaching staff and track pitches with Minor Leaguers. Mills said they're both going to Viera, Fla., for Thursday's game against the Nationals.
